Abstract: 547,130. Cracking oils. STANDARD OIL DEVELOPMENT CO. Feb. 10, 1941, No. 1737. Convention date, Dec. 9, 1939. [Class 32] In processes for the catalytic conversion of hydrocarbon oil in the vapour phase of the kind in which a suspension of the oil vapours and finely divided solid catalyst is passed through a reaction zone the oils are preheated to incipient cracking temperatures and are then brought rapidly to the required cracking temperatures by injecting therein powdered solid catalyst heated to the required temperatures to bring the mixed vapours to the required cracking temperatures. Crude oil fed through line 10 is vaporized in a tubular furnace 13 and with or without passage through a separator 15 is passed through a line 17 where it is mixed with catalyst fed from a conveyer 19 and heated to the required temperature the mixture passing into a reactor 18. The suspension of cracked products and catalyst is passed to a cyclone separator. 21 from which vapours pass to a fractionating tower 23 from which gasoline fractions are recovered through line 28 and condenser to receiver 30. A plurality of cyclone separators may be used. The separated catalyst falls through star feeder 34 to a purging chamber 36 where residual vapours are stripped from the catalyst by steam injected through line 37, the vapours and steam being removed through line 38. The purged catalyst is removed through valve 39 to an intermediate section 40 maintained at higher pressure than the section 35, a pressure equalizing line 41 being provided so that pressure can be equalized before discharging the catalyst into section 40. The catalyst is finally discharged to a lower pressure zone 44 from which it is passed by conveyer 47 into the regeneration zone 50 supplied with air or other gases containing oxygen by a blower 49. The regenerated catalyst is then passed through cyclone 52 into a tower 58 having sections constructed and maintained at differential pressures as described with reference to tower 36. A heat exchanger coil 67 is provided to bring the purged catalyst to the required temperature for admixture with the vapours in the line 17. In an example oil vapours at 800 F. are raised to 900 F. by mixing them with catalyst at 1000 F. the proportion of catalyst to oil being 4 to 1 by weight. Specifications 261,786, [Class 32], and 525,443, are referred to.
